THRESHOLD IMPACT VELOCITY UNDER THE ASSUMPTION OF CONSTANT RESISTIVE FORCE IN THE PENETRATION OF A RIGID PROJECTILE
(0) According to the dimensionless formula of DOP(depth of penetration) of different targets penetrated by a rigid projectile, the present paper theoretically analyses the resistive force which the target exerts on the projectile during the penetration of a rigid projectile. In particular, the threshold Vc of impact velocity applicable for the assumption of constant resistive force is formulated by impulse analysis. The various values of Vc of different pairs of projectile-target are calculated out and consistence with relative numerical results is observed.
